Article describing a study of the potential to use heat pumps to heat and cool homes across the United States, including cold climate locations like Alaska.

Guide describing proper application, design, and installation of mechanical ventilation cooling systems for homes located in hot-dry and cold-dry climates, as well as a means of understanding the benefits, costs, and tradeoffs of these systems.

Expert meeting held to discuss simplified space conditioning systems in low load homes, including the relationship between advanced thermal enclosures, space conditioning systems and comfort.

Report evaluating HVAC building technologies based on their ability to provide grid services and the type of value provided, including efficiency, load shed, load shift, and modulation.

Report on a project conducted to better understand the current usage of thermostatic radiator valves by key market players in steam and hot water heating and to conduct limited experiments on the effectiveness of new and old thermostatic radiator valves as a means of controlling space temperatures...

Standard 55 specifies conditions for acceptable thermal environments and is intended for use in design, operation, and commissioning of buildings and other occupied spaces; is the current version of the standard, which was published in the year 2021, and is available for preview and purchase at the...

Report describing two retrofit duct sealing techniques - manually-applied sealants and injecting a spray sealant, that were implemented in several low-rise multi-unit buildings in North Carolina.

This document addresses adding—or improving—mechanical ventilation systems to existing homes. The purpose of ventilation is to remove contaminants from homes either directly or by dilution. This report discusses where, when, and how much ventilation is appropriate in a home, including some...

Report providing information about energy-efficient heating, ventilation, and cooling (HVAC) equipment options to help homeowners cut their energy use, reduce their carbon footprint, and increase their homes comfort, health, and safety.

Fact sheet describing best strategies to bring ductwork on single-story homes with a slab-on-grade foundation in hot, dry climates into the conditioned envelope of the home intending to highlight the pros and cons of multiple ductwork integration strategies, including traditional duct systems in...

Document intending to put some context and structure around the process of balancing and tuning one-pipe steam systems to help practitioners begin to garner the potential in energy savings that this measure presents.

Report addressing barriers to information, contractor resources and cost savings associated with steam balancing multifamily buildings.

Technical report describing the evaluation of four different ventilation strategies for providing make-up air in high-performance, new construction multifamily buildings in the Northeast, emphasizing the challenges posed by increasing airtightness standards and the variability of system performance...

Document illustrating guidelines for efficient installation of interior duct systems in new housing.

Report on experiments comparing the cooling and heating seasonal and peak demand performance of different variable-capacity air conditioning and heat pump units.

Report identifying two barriers that limit the ability of builders to explore opportunities for higher levels of energy efficiency in housing: the use of duct system materials that inherently achieve airtightness and are right-sized for low-load houses, and, the ability to air seal fire separation...

Report outlining how Smart ventilation controls (SVC) balance energy consumption, comfort, and IAQ by optimizing mechanical ventilation operation to reduce the heating and/or cooling loads, improve management of indoor moisture, and maintain IAQ equivalence according to ASHRAE 62.2.

Report focusing on managing the driving forces that move air and water vapor across the building envelope.

Report of a field evaluation of four novel roof designs to see how each design would reduce space-conditioned energy use so that the knowledge gained could be applied to the design of new manufactured homes.

This ANSI/RESNET/ICC standard provides a consistent, uniform methodology for evaluating the airtightness of building, dwelling unit, and sleeping unit enclosures and heating and cooling air distribution systems, and the air flows of mechanical ventilation systems.

Research study describing experiments run in an unoccupied 1600 square foot house to evaluate the delivered performance as well as the relative performance of a SEER 21 variable capacity heat pump versus a SEER 13 heat pump.
